Cryptosporidium, enterocytozoon, and cyclospora infections in pediatric and adult patients with diarrhea in Tanzania. (1/928)

Cryptosporidiosis, microsporidiosis, and cyclosporiasis were studied in four groups of Tanzanian inpatients: adults with AIDS-associated diarrhea, children with chronic diarrhea (of whom 23 of 59 were positive [+] for human immunodeficiency virus [HIV]), children with acute diarrhea (of whom 15 of 55 were HIV+), and HIV control children without diarrhea. Cryptosporidium was identified in specimens from 6/86 adults, 5/59 children with chronic diarrhea (3/5, HIV+), 7/55 children with acute diarrhea (0/7, HIV+), and 0/20 control children. Among children with acute diarrhea, 7/7 with cryptosporidiosis were malnourished, compared with 10/48 without cryptosporidiosis (P < .01). Enterocytozoon was identified in specimens from 3/86 adults, 2/59 children with chronic diarrhea (1 HIV+), 0/55 children with acute diarrhea, and 4/20 control children. All four controls were underweight (P < .01). Cyclospora was identified in specimens from one adult and one child with acute diarrhea (HIV-). Thus, Cryptosporidium was the most frequent and Cyclospora the least frequent pathogen identified. Cryptosporidium and Enterocytozoon were associated with malnutrition. Asymptomatic fecal shedding of Enterocytozoon in otherwise healthy, HIV children has not been described previously.  (+info)

Cytokine profile induced by Cryptosporidium antigen in peripheral blood mononuclear cells from immunocompetent and immunosuppressed persons with cryptosporidiosis. (2/928)

The proliferative response of peripheral blood mononuclear cells (PBMC) to a crude extract from Cryptosporidium parvum (CCE) was studied in persons who acquired cryptosporidiosis in the same outbreak (15 immunocompetent subjects with prior cryptosporidiosis and 22 human immunodeficiency virus [HIV]-positive persons with various levels of immunosuppression and active cryptosporidiosis) and in individual patients (8 HIV-positive patients with active cryptosporidiosis and 15 HIV-positive persons without history of cryptosporidiosis). PBMC from HIV-positive persons showed less proliferation to CCE and mitogens than did PBMC from immunocompetent subjects with prior cryptosporidiosis, independent of CD4 cell count. In immunocompetent subjects, cytokine gene expression was consistent with cytokine production, whereas in HIV-positive subjects it was not. The production of interferon-gamma in CCE-stimulated PBMC from both immunocompetent and HIV-positive subjects with cryptosporidiosis and the lack of interferon-gamma in CCE-stimulated PBMC from HIV-positive subjects without cryptosporidiosis indicate that C. parvum mainly induces a Th1 response.  (+info)

Identification of Cryptosporidium felis in a cow by morphologic and molecular methods. (3/928)

Apicomplexan Cryptosporidium parasites infect a wide range of vertebrate hosts. While some species are limited to a single host group, such as Cryptosporidium baileyi, which infects chickens, other species of this genus, such as C. parvum, infect a wide range of mammalian species from mice to humans. During an investigation of Cryptosporidium infection in cattle on a farm in northern Poland, we identified an infection caused by C. felis, in addition to known infections with C. muris and C. parvum. This new infection was identified based on the size of the oocysts (mean size, 4.3 +/- 0.4 micrometer; range, 3.5 to 5.0 micrometer), as well as by analysis of the molecular sequence of the variable region of the small-subunit rRNA. This finding demonstrates the complex host specificity and circulation in the environment of Cryptosporidium species.  (+info)

Phylogenetic analysis of Cryptosporidium parasites based on the small-subunit rRNA gene locus. (4/928)

Biological data support the hypothesis that there are multiple species in the genus Cryptosporidium, but a recent analysis of the available genetic data suggested that there is insufficient evidence for species differentiation. In order to resolve the controversy in the taxonomy of this parasite genus, we characterized the small-subunit rRNA genes of Cryptosporidium parvum, Cryptosporidium baileyi, Cryptosporidium muris, and Cryptosporidium serpentis and performed a phylogenetic analysis of the genus Cryptosporidium. Our study revealed that the genus Cryptosporidium contains the phylogenetically distinct species C. parvum, C. muris, C. baileyi, and C. serpentis, which is consistent with the biological characteristics and host specificity data. The Cryptosporidium species formed two clades, with C. parvum and C. baileyi belonging to one clade and C. muris and C. serpentis belonging to the other clade. Within C. parvum, human genotype isolates and guinea pig isolates (known as Cryptosporidium wrairi) each differed from bovine genotype isolates by the nucleotide sequence in four regions. A C. muris isolate from cattle was also different from parasites isolated from a rock hyrax and a Bactrian camel. Minor differences were also detected between C. serpentis isolates from snakes and lizards. Based on the genetic information, a species- and strain-specific PCR-restriction fragment length polymorphism diagnostic tool was developed.  (+info)

beta-tubulin mRNA as a marker of Cryptosporidium parvum oocyst viability. (5/928)

Determining the viability of waterborne Cryptosporidium parvum oocysts remains a technical challenge. rRNA and mRNA were evaluated in a reverse transcription (RT)-PCR assay as potential markers of oocyst viability. The rationale for this approach is the rapid turnover and postmortem decay of cellular RNA. The beta-tubulin mRNA and an anonymous mRNA transcript were chosen as potential markers because they are the only mRNA species in C. parvum known to possess introns. This feature facilitated the distinction between genuine RT-PCR products and PCR products originating from copurifying DNA. Prolonged incubation at room temperature of initially viable oocysts resulted in a gradual decrease in mRNA levels, which correlated with the loss of oocyst infectivity to neonatal mice. In contrast, oocysts stored at 4 degrees C for over 39 weeks maintained their infectivity and displayed no decrease in the level of beta-tubulin RT-PCR product. The postmortem decay of two mRNA species demonstrates that RT-PCR analysis can provide information on the viability of C. parvum oocysts. The methodological similarity between PCR detection and RT-PCR viability analysis could facilitate the development of a combined detection and viability assay.  (+info)

Age-dependent resistance to Cryptosporidium muris (strain MCR) infection in golden hamsters and mice. (6/928)

An age-dependent aspect of resistance to Cryptosporidium muris (strain MCR) infection was monitored in Syrian golden hamsters, Mesocricetus auratus, at 1-, 5- and 10-week of age and in ICR mice. Mus musculus, at 3-, 12-, and 15-week of age orally inoculated with a single dose of 2 x 10(6) oocysts, respectively. The prepatent periods for both animals were similar, independent of age, but the patency was significantly longer in younger hamsters (P < 0.001) and a long tendency in younger mice. Hamsters infected at 1-week of age excreted about 10 times higher oocysts than those at 5- and 10-week of age. However, the total oocyst output was similar among mice of different ages. There was a good correlation between the length of the patency and the total oocyst output in hamsters (R = 0.9646), but not in mice (R = 0.4561). The immunogenicity of the parasite to homologous challenge infections was very strong in hamsters and relatively strong in mice. These results indicate that acquired resistance to C. muris infection is age-related and the innate resistance is independent of age of hamsters, and that both innate and acquired resistance, on the contrary, are irrespective of age of mice.  (+info)

Use of a sentinel system for field measurements of Cryptosporidium parvum oocyst inactivation in soil and animal waste. (7/928)

A small-volume sentinel chamber was developed to assess the effects of environmental stresses on survival of sucrose-Percoll-purified Cryptosporidium parvum oocysts in soil and animal wastes. Chambers were tested for their ability to equilibrate with external chemical and moisture conditions. Sentinel oocysts were then exposed to stresses of the external environment that affected their viability (potential infectivity), as indicated by results of a dye permeability assay. Preliminary laboratory experiments indicated that temperatures between 35 and 50 degrees C and decreases in soil water potential (-0.003 to -3.20 MPa) increased oocyst inactivation rates. The effects of two common animal waste management practices on oocyst survival were investigated on three dairy farms in Delaware County, N.Y., within the New York City watershed: (i) piling wastes from dairy youngstock (including neonatal calves) and (ii) spreading wastes as a soil amendment on an agricultural field. Sentinel containers filled with air-dried and sieved (2-mm mesh) youngstock waste or field soil were wetted and inoculated with 2 million oocysts in an aqueous suspension and then placed in waste piles on two different farms and in soil within a cropped field on one farm. Controls consisted of purified oocysts in either phosphate-buffered saline or distilled water contained in sealed microcentrifuge tubes. Two microdata loggers recorded the ambient temperature at each field site. Sentinel experiments were conducted during the fall and winter (1996 to 1997) and winter (1998). Sentinel containers and controls were removed at 2- to 4-week intervals, and oocysts were extracted and tested by the dye permeability assay. The proportions of potentially infective oocysts exposed to the soil and waste pile material decreased more rapidly than their counterpart controls exposed to buffer or water, indicating that factors other than temperature affected oocyst inactivation in the waste piles and soil. The effect of soil freeze-thaw cycles was evident in the large proportion of empty sentinel oocysts. The potentially infective sentinel oocysts were reduced to <1% while the proportions in controls did not decrease below 50% potentially infective during the first field experiment. Microscopic observations of empty oocyst fragments indicated that abrasive effects of soil particles were a factor in oocyst inactivation. A similar pattern was observed in a second field experiment at the same site.  (+info)

CpABC, a Cryptosporidium parvum ATP-binding cassette protein at the host-parasite boundary in intracellular stages. (8/928)

The intracellular parasite Cryptosporidium parvum develops inside a vacuole at the apex of its epithelial host cell. The developing parasite is separated from the host cell cytoplasm by a zone of attachment that consists of an extensively folded membranous structure known as the feeder organelle. It has been proposed that the feeder organelle is the site of regulation of transport of nutrients and drugs into the parasite. In this report, we localize an approximately 200-kDa integral membrane protein, CpABC, from Cryptosporidium parvum to the host-parasite boundary, possibly the feeder organelle. The predicted amino acid sequence of CpABC has significant structural similarity with the cystic fibrosis conductance regulator and the multidrug resistance protein subfamily of ATP-binding cassette proteins. This is an example of a parasite-encoded transport protein localized at the parasite-host interface of an intracellular protozoan.  (+info)

In November 1982, 21 patients with acquired immunodeficiency syndrome (AIDS) and severe, protracted diarrhea caused by cryptosporidiosis were reported; the report concluded that no effective treatment for cryptosporidiosis was known at that time (1). Since then, 91 additional AIDS patients with chronic cryptosporidiosis have been reported to CDC. Although no therapy has been consistently effective in treating them, preliminary reports suggest that a few may have responded to treatment with spiramycin (Rovamycine,* Rhone-Poulenc Pharma, Montreal) or the combination of quinine and clindamycin. Since December 1982, physicians at the University of Miami, Florida, have used spiramycin to treat seven AIDS patients with chronic cryptosporidiosis; six other AIDS patients with cryptosporidiosis have been treated with spiramycin at five other institutions; and one non-AIDS patient with chronic cryptosporidiosis associated with a bone marrow transplant has received the drug.

The incidence of sporadic cryptosporidiosis among 106,000 residents of 2 local government districts in northwest England before and after installation of membrane filtration of public water supplies was compared to that of 59,700 residents whose public water supplies remained unchanged. A national outbreak of foot and mouth disease in livestock during 2001 was associated with a decline in sporadic human cryptosporidiosis in all regions of the United Kingdom. In a Poisson regression model, membrane filtration was associated with an estimated 79% reduction (incidence ratio 0.207, 95% confidence intervals 0.099-0.431, p &lt; 0.0001) after adjustment for the interval of the foot and mouth disease epidemic and the water source. Despite the confounding effect of that epidemic, membrane filtration of the public water supply was effective in reducing the risk for sporadic human Cryptosporidium infection in this population.
National surveillance data are used to help characterize the epidemiology of cryptosporidiosis in the United States. In 2009 and 2010, the total number and rate of cases reported annually decreased from that of 2007, but represent a marked increase compared with annual statistics before 2005 (Figure 1). Whether the persistently elevated annual case counts and rates reflect changes in diagnostic testing practices, reporting patterns, or a change in infection and disease caused by Cryptosporidium remains unclear. The increased annual number of reported cases and rates during 2005-2010 might be the result of an increase in the number of communitywide and large (e.g., ,1,000 cases) cryptosporidiosis outbreaks (24,43-51). Further, 2009 and 2010 had the lowest annual proportion of cases reported to be associated with detected cryptosporidiosis outbreaks since national reporting began in 1995 (32-35). This coincided with a decrease in the number of reported communitywide and large cryptosporidiosis ...
To improve understanding of the aetiology and epidemiology of human cryptosporidiosis, over 8,000 Cryptosporidium isolates were submitted for typing to the species level over a four year period. The majority were either Cryptosporidium parvum (45.9%)
We used the Temporal Exposure Response Surfaces modeling technique to examine the association between gastroenteritis-related emergency room visits and hospitalizations in the elderly and drinking water turbidity before and during the 1993 Milwaukee waterborne Cryptosporidium outbreak. Before the outbreak, the rate of such events increased with age in the elderly (p&lt;0.002), suggesting that the elderly are at an increased risk. During the outbreak, strong associations between turbidity and gastroenteritis-related emergency room visits and hospitalizations occurred at temporal lags of 5-6 days (consistent with the Cryptosporidium incubation period). A pronounced second wave of these illnesses in the elderly peaked at 13 days. This wave represented approximately 40% of all excess cases in the elderly. Our findings suggest that the elderly had an increased risk of severe disease due to Cryptosporidium infection, with a shorter incubation period than has been previously reported in all adults and with
Cryptosporidium parvum, an intracellular protozoan parasite, is a frequent cause of chronic diarrhea in HIV-infected patients, causing significant morbidity and mortality. Highly effective antiparasitic treatment for this infection is not currently available. Paromomycin and azithromycin have some efficacy and have been used in combination in a small number of patients. Immune reconstitution with highly active antiretroviral therapy appears to be the most effective therapy, but this is not possible for all patients. Interferon gamma expression is strongly associated with control of cryptosporidiosis, and IL-12 is the cytokine primarily responsible for stimulation of interferon gamma expression in vivo. It is hoped that treatment with recombinant human IL-12 can result in stimulation of an intestinal cytokine response in AIDS patients with cryptosporidiosis and that response combined with chemotherapy can lead to the elimination of detectable numbers of Cryptosporidium oocysts from the ...

Cryptosporidium species causes asymptomatic or mild to severe gastrointestinal disease in their broad range of host species. These host species include humans, domestic and wild animals worldwide. The importance of cryptosporidiosis in ruminants has been emphasised in recent years for not only mortality, delayed growth and economic losses in the farm but also zoonotic importance. So more than 200 substances have been tested against cryptosporidiosis, but none of them was able to eliminate the infection consistently. This article will focus on therapeutic interventions in neonatal ruminants against cryptosporidiosis including perspectives for new drugs.
During 2014, 337 cases of cryptosporidiosis (6.2 per 100,000 population) were reported. This is 11% higher than the median number of cases reported annually from 2004 to 2013 (median, 304.5 cases; range, 147 to 389). The median age of cases in 2014 was 24 years (range, 9 months to 99 years). Children 10 years of age or younger accounted for 29% of cases. Sixty-one percent of cases occurred during July through October. The incidence of cryptosporidiosis in the West Central, Southwestern, Northeastern, Southeastern, and Northwestern districts (25.3, 12.8, 11.3, 11.2, and 10.7 cases per 100,000, respectively) was significantly higher than the statewide incidence. Only 70 (21%) cases occurred among residents of the metropolitan area (2.4 per 100,000). Forty-five (13%) cases required hospitalization, for a median of 4 days (range, 2 to 13 days). Seven outbreaks of cryptosporidiosis were identified in Minnesota in 2014, accounting for 22 laboratory-confirmed cases. One recreational water outbreak ...

In 2007, a waterborne outbreak of Cryptosporidium hominis infection occurred in western Ireland, resulting in 242 laboratory-confirmed cases and an uncertain number of unconfirmed cases. A boil water notice was in place for 158 days that affected 120,432 persons residing in the area, businesses, visitors, and commuters. This outbreak represented the largest outbreak of cryptosporidiosis in Ireland. The purpose of this study was to evaluate the cost of this outbreak. We adopted a societal perspective in estimating costs associated with the outbreak. Economic cost estimated was based on totaling direct and indirect costs incurred by public and private agencies. The cost of the outbreak was estimated based on 2007 figures. We estimate that the cost of the outbreak was >€19 million (≈€120,000/day of the outbreak). The US dollar equivalent based on todays exchange rates would be $22.44 million (≈$142,000/day of the outbreak). This study highlights the economic need for a safe drinking water ...

Cryptosporidiosis, also known as crypto, is a parasitic disease caused by Cryptosporidium, a genus of protozoan parasites in the phylum Apicomplexa. It affects the distal small intestine and can affect the respiratory tract in both immunocompetent (i.e., individuals with a normal functioning immune system) and immunocompromised (e.g., persons with HIV/AIDS or autoimmune disorders) individuals, resulting in watery diarrhea with or without an unexplained cough. In immunocompromised individuals, the symptoms are particularly severe and can be fatal. It is primarily spread through the fecal-oral route, often through contaminated water; recent evidence suggests that it can also be transmitted via fomites in respiratory secretions. Cryptosporidium is the organism most commonly isolated in HIV-positive patients presenting with diarrhea.[medical citation needed] Despite not being identified until 1976, it is one of the most common waterborne diseases and is found worldwide. The parasite is transmitted ...
One of the most common waterborne diseases worldwide is cryptosporidiosis, a parasitic disease affecting the small intestine and possibly our airways. It is a common cause of diarrhoea in HIV-positive patients, who are known to have lower immunity. Now Kazeem Oare Okosun from Vaal University of Technology in South Africa and colleagues from Pakistan and Nigeria have developed a new model and numerical simulations to determine the optimal combination of prevention and treatment strategies for controlling both diseases in patients who have been co-infected. Their results, recently published in EPJ Plus, show a positive impact on the treatment and prevention for cryptosporidiosis alone, for HIV-AIDS alone, or for both together. Although there are many mathematical models on HIV infection, there are far fewer for cryptosporidiosis. And, until now, there was no co-infection model for cryptosporidiosis and HIV-AIDS. The authors examined what happens to patients presenting both infections when they are ...

Cryptosporidia are small coccidian parasites that infect the mucosal epithelia of a variety of vertebrate hosts, including humans, affecting the health, survival, and economic development of millions of people and animals worldwide. Human infection is mainly caused by two species: (1) Cryptosporidium parvum-also prevalent in young livestock; can be transmitted from animals to humans (zoonotic transmission, particularly important in children), from person to person (urban cycle, due to faecal-oral spread), through contamination of public drinking-water supplies (which can produce massive outbreaks) or food (prepared by a sick food handler), and nosocomially.

The aim of the study was to investigate the social and gender determinants of the risk of exposure to Cryptosporidium from urban dairying in Dagoretti, Nairobi. Focus group discussions were held in six locations to obtain qualitative information on risk of exposure. A repeated cross-sectional descriptive study included participatory assessment and household questionnaires (300 randomly selected urban dairy farming households and 100 non-dairying neighbours). One-hundred dairy households randomly selected from the 300 dairy households participated in an additional economic survey along with 40 neighbouring non-dairy households. We found that exposure to Cryptosporidium was influenced by gender, age and role in the household. Farm workers and people aged 50 to 65 years had most contact with cattle, and women had greater contact with raw milk. However, children had relatively higher consumption of raw milk than other age groups. Adult women had more daily contact with cattle faeces than adult men, ...

There have been numerous reports of swimming pool-associated outbreaks of Cryptosporidiosis and Giardiasis worldwide, including Australia. It is essential to ensure that effective measures are in place to manage faecal contamination incidents, the primary source of contamination of these pathogens in public swimming pools. There are no evidence-based guidelines for the management of faecal contamination incidents (FCI) in public swimming pools in Australia. The aim of the study is to develop, implement and evaluate guidelines to reduce the public health risk associated with Cryptosporidium and Giardia in public swimming pools in Australia. This research is particularly important both nationally and internationally as the endemic of Cryptosporidium and Giardia is increasing significantly. It is estimated that half of all Indigenous children are affected by these pathogens which can cause long-term disability or death. A random sample of public swimming pools from metropolitan, rural and remote ...

INPANKAEW, T. et al. Seroprevalence of Cryptosporidium parvum infection of dairy cows in three northern provinces of Thailand determined by enzyme-linked immunosorbent assay using recombinant antigen CpP23. Onderstepoort j. vet. res. [online]. 2009, vol.76, n.2, pp.161-165. ISSN 2219-0635.. Cryptosporidium parvum is the most frequent parasitic agent that causes diarrhoea in AIDS patients in Thailand. Cryptosporidiosis outbreaks in humans may be attributed to contamination of their drinking water from infected dairy pastures. A 23-kDa glycoprotein of C. parvum (CpP23) is a sporozoite surface protein that is geographically conserved among C. parvum isolates. This glycoprotein is a potentially useful candidate antigen for the diagnosis of cryptosporidiosis by enzyme-linked immunosorbent assay. Therefore, we investigated the seroprevalence of C. parvum infection in dairy cows in northern Thailand using an ELISA based on recombinant CpP23 antigen. Sera were randomly collected from 642 dairy cows of ...
The apicomplexan parasites Cryptosporidium parvum and C. hominis are major etiologic agents of human cryptosporidiosis. Infection is typically self-limited in immunocompetent adults, but can cause chronic, fulminant diarrhea in immunocompromised patients, and malnutrition and stunting in children. Nitazoxanide, the current standard-of-care for cryptosporidiosis, is only partially efficacious for children and is no more effective than placebo in AIDS patients. Unfortunately, financial obstacles to drug discovery for diseases that disproportionately affect low-income countries and technical limitations associated with studies of Cryptosporidium biology both impede development of better drugs for cryptosporidiosis. Using a cell-based high-throughput screen, we queried the Medicines for Malaria Ventures (MMV) "Open Access Malaria Box" for activity against C. parvum. We identified 3 novel chemical series derived from the quinolin-8-ol, allopurinol-based, and 2,4-diamino-quinazoline chemical ...

Cryptosporidium spp. are important zoonotic pathogens, causing enterocolitis and diarrhea in children and immunocompromised persons. In developing countries, cryptosporidiosis is one of the most important causes of moderate to severe diarrhea and diarrhea-associated death. In industrialized nations, Cryptosporidium spp. are well recognized waterborne, foodborne, and zoonotic pathogens, having caused many outbreaks of human illness. In the United States, the number of annual reported cases of cryptosporidiosis has increased more than 2-fold in recent years. In this chapter, various laboratory techniques for the detection and diagnosis of Cryptosporidium spp. and the most recent progress in Cryptosporidium taxonomy and the molecular epidemiology and treatment of cryptosporidiosis are reviewed.
Status. The initial version of the C. muris WGS sequence has been deposited at GenBank.. Background. The genus Cryptosporidium, a group of single-celled eukaryotic organisms in the phylum Apicomplexa, comprises an unknown number of species infecting numerous vertebrate species. It includes two groups of parasites that have adapted to different environments in the gastrointestinal (GI) tract: the small intestine/colon, where the majority of species multiply, and the stomach, which only a few species are able to infect. Cryptosporidium species are significant sources of gastrointestinal infection worldwide. Particularly in underdeveloped nations, cryptosporidiosis is common in children, where it is frequently associated with persistent diarrhea, malnutrition and stunted growth (Guerrant 1997). In immune compromised individuals, persistent infection with Cryptosporidium can lead to wasting and is often fatal. Effective drugs or vaccines against this infection are not available (Tzipori 1998). The ...
Abstract The occurrence of a massive waterborne outbreak of Cryptosporidium infection in Milwaukee, Wisconsin provided an opportunity to evaluate the effectiveness of point-of-use home water filters in preventing diarrheal illness associated with Cryptosporidium infection. Of 155 filter owners who responded to a televised request to contact the City of Milwaukee Health Department, 99 (64%) completed a self-administered questionnaire regarding their sources of drinking water, the characteristics of their home water filters, and diarrheal illness during the outbreak. Diarrhea among respondents was independently associated with residence in southern or central Milwaukee (the area served by the implicated South water treatment plant), having a home water filter with a pore diameter of greater than 1 µm, and drinking unfiltered tap water in a public building in southern Milwaukee. Among residents of southern and central Milwaukee, two (18%) of 11 persons who drank only submicron-filtered water at home and
In April 2013, the Thomas County Health Department notified the Kansas Department of Health and Environments Infectious Disease Epidemiology and Response section (KDHE) of two cases of cryptosporidiosis among emergency responders to a tractor-trailer rollover. The truck was carrying approximately 350 preweaned Holstein calves. An outbreak investigation was led by KDHE with assistance from the county health department; six cases of cryptosporidiosis were identified among the 15 emergency responders. No additional primary cases with this exposure or secondary cases were identified. Disease was associated with carrying calves (relative risk [RR] = 3.0) and contact with fecal matter (RR = 4.5). The calves were aged |10 days and reportedly suffered from scours (diarrheal disease), which is often caused by Cryptosporidium spp., a chlorine-tolerant protozoan parasite. Because of the age of the calves and the conditions at the rollover scene, a high potential existed for fecal contamination and subsequent
There were 11 (10.5%) individuals with Cryptosporidium-sp-positive fecal samples, one in G1, three in G2, and seven in G3; there were no significant differences among groups (p,0.05). It is noteworthy that the number of oocysts was small in all individuals who tested positive for Cryptosporidium sp. Diarrhea was found in 12 (11.4%) individuals. There was no significant difference among groups (p,0.05); however, there was a higher tendency towards diarrhea in G1 and G2. Five out of the 12 individuals with diarrhea tested positive for Cryptosporidium sp. Only seven (6.7%) individuals lived in the rural zone; all cases of Cryptosporidium sp were in feces from urban zone dwellers.. DISCUSSION. In Brazil, AIDS has predominantly affected men since the beginning of the epidemic, a fact also noticed in the current study.

Objectives: To evaluate the efficacy of nitazoxanide and paromomycin in biliary tract cryptosporidiosis in an immunosuppressed Mongolian gerbil (Meriones unguiculatus) model.. Methods: Gerbils (1-month-old) were dexamethasone-immunosuppressed for 10 days and challenged orally with 105 Cryptosporidium parvum oocysts. From day 0 to day 12 post-infection, one group (n = 14) was treated with 200 mg/kg/day nitazoxanide and another (n = 15) with 100 mg/kg/day paromomycin. Infection and efficacy of nitazoxanide and paromomycin were assessed by measuring oocyst shedding in faeces, biliary tract and ileum histological examination.. Results: In nitazoxanide-treated and paromomycin-treated groups as compared with untreated animals (P , 0.05), oocyst shedding was partially suppressed in a similar manner (P , 0.05). Parasites were present in histological sections of the ileal mucosa of 16/16 infected untreated animals versus 3/14 and 6/15 in the nitazoxanide-treated and the paromomycin-treated groups, ...
Purpose. Conventional laboratory detection methods for gastrointestinal parasites are time consuming, require considerable technical expertise and may suffer from poor analytical sensitivity. This study sought to evaluate the automated BD MAX Enteric Parasite Panel (EPP) for the detection of Cryptosporidium parvum/hominis, Entamoeba histolytica and Giardia duodenalis. Methodolgy. A total of 104 known positive samples (43 Cryptosporidium parvum/hominis and 61 G . duodenalis), 15 simulated samples (E. histolytica and other Entamoeba species) and 745 patient stool samples, submitted for enteric pathogen culture and microscopy, were inoculated into BD MAX EPP sample buffer tubes (SBTs). All specimens were blinded and tested within 7 days of SBT inoculation using the BD MAX EPP assay with results compared to those generated by microscopy. Results/Key findings. Combining the results from the known positive samples and anonymously tested patient samples, the sensitivity of the BD MAX EPP assay was 100 % for
BACKGROUND: The association between Cryptosporidium and human colon cancer has been reported in different populations. However, this association has not been well studied. In order to add new strong arguments for a probable link between cryptosporidiosis and colon human cancer, the aim of this study was to determine prevalence and to identify species of Cryptosporidium among Lebanese patients. METHODOLOGY AND PRINCIPAL FINDINGS: Overall, 218 digestive biopsies were collected in Tripoli, Lebanon, from three groups of patients: (i) patients with recently diagnosed colon intraepithelial neoplasia/adenocarcinoma before any treatment (n = 72); (ii) patients with recently diagnosed stomach intraepithelial neoplasia/adenocarcinoma before any treatment (n = 21); and (iii) patients without digestive intraepithelial neoplasia/adenocarcinoma but with persistent digestive symptoms (n = 125 ...
Abstract Text: Cryptosporidium is a protozoan parasite that causes enteric infection in several mammalian species, including humans. This infection has a major impact in immunocompromised domestic mammals and public health because the parasite oocysts are resistant to environment and can contaminate food and water. In sheep, cryptosporidiosis is presented with mild to severe yellowish diarrhea, plus weight loss, depression, abdominal pain, and eventually the animal may die; usually, it is more common in lambs 1-30 days old. Therefore, the objective of this study was to determine the prevalence of Cryptosporidium spp., and identify the species of the oocysts in lambs maintained in extensive grazing systems at the Huasteca Alta region, State of Veracruz, Mexico. From March to June 2012, two hundred and ten fecal samples were collected from Blackbelly x Pelibuey lambs 7-21 days old, from 21 flocks located in seven locations at the Huasteca Alta region. The samples were processed by performing a ...

Cryptosporidiosis or Crypto is an illness caused by a parasite that lives in soil, food and water. Learn the common symptoms and what you should do.
Once thought to be rare and host specific, Cryptosporidia is now believed to be one of the top three diarrheal causing pathogens in the world. Cryptosporidia muris was recognized in 1907 by E. E. Tyzer. Since then twenty (20) species of Cryptosporidium have been discovered and named although recently sixteen (16) of those twenty (20) have come under speculation due to recent cross-transmission studies. Cryptosporidia is a protozoan parasite which lives in the intestines and respiratory epitheliums of many types of animals including mammals, birds and reptiles. The disease caused by Cryptosporidia is known as Cryptosporidiosis. Cryptosporidia is found all over the world and is transmitted via fecal oral contact. Usually this is due to water contaminated by animal feces. Infected calves excrete up to 10 billion Cryptosporidium oocysts (infectious stage) per day. The infectious dose in humans is only 10-100.

A. Cryptosporidium is a microscopic organism which exists in the environment in a form called an oocyst. These oocysts are tiny - less than one-tenth the thickness of a human hair! The parasite is commonly found in cattle, sheep, humans and many other mammals as well as birds, fish and reptiles. These oocysts, if ingested, can cause a gastrointestinal illness called cryptosporidiosis. People most commonly develop cryptosporidiosis after coming into contact an infected animal (including domestic pets), or an infected person, or by consuming contaminated food, milk or water. Many recent outbreaks have been associated with swimming in contaminated pools both in the UK and abroad. We minimise the risk from Cryptosporidium by protecting our raw water sources from contamination by careful catchment management. Any cryptosporidium oocysts which do make it to our raw water are removed by the treatment processes we use at our water treatment works.. Q. What are you currently doing to get our water ...
Used alone, UV radiation does not improve the taste, odor, or clarity of water. UV light is a very effective disinfectant, although the disinfection can only occur inside the unit. There is no residual disinfection in the water to inactivate bacteria that may survive or may be introduced after the water passes by the light source. The percentage of microorganisms destroyed depends on the intensity of the UV light, the contact time, raw water quality, and proper maintenance of the equipment. If material builds up on the glass sleeve or the particle load is high, the light intensity and the effectiveness of treatment are reduced. At sufficiently high doses, all waterborne enteric pathogens are inactivated by UV radiation.

Fifty-one of the regulated genes were associated with apoptosis and were grouped into f ...
More than 1,900 holidaymakers recovered over £3.2 million after an outbreak of cryptosporidiosis at the Alcudia Pins Hotel, Majorca. A number of holidaymakers were left with long term symptoms including irritable bowel syndrome. We were successful in recovering damages from tour operator My Travel on behalf of over 1,900 holidaymakers who stayed at the Alcudia Pins Hotel, Majorca between June and September 2003 after their holidays were ruined by an outbreak of cryptosporidiosis. Holidaymakers complained about the quality of the accommodation, attitude of the hotel staff and tour operator representatives, cleanliness in and around the swimming pools and poor food hygiene standards. On 23 July 2003, after hundreds of guests had fallen ill with gastric symptoms, a water sample was taken from the hotels main swimming pool and tested. The results revealed that the pool was contaminated with the waterborne parasite cryptosporidium. The swimming pool was closed for 2 weeks and disinfected. Despite ...
Cryptosporidium completes its life cycle within a single host1,11(Fig. 345-1). Infection occurs after ingesting the sporulated, thick-walled oocysts. Excystation occurs in the small intestine after exposure to bile salts and pancreatic enzymes, releasing four sporozoites. These sporozoites penetrate a surface epithelial cell in the intestinal mucosa and form an intracellular parasitophorous vacuole. They then differentiate into uninuclear trophozoites, which undergo asexual replication (merogony) to form type I meronts. The type I meront can then autoinfect other surface epithelial cells or differentiate into a type II meront. The type II meront then undergoes gametogomy, producing both microgametocytes and macrogametocytes. These gametocytes fertilize to produce oocysts. The life cycle is complete when the oocysts undergo sporogomy, resulting in infectious sporozoites within the oocysts. Approximately 80% of the oocysts produced in this fashion are environmentally resistant, thick-walled cysts ...

Treatments for protozoal-induced diarrhea have been expanded in recent decades. The realization that protozoa infections can cause long-term morbidity in children has garnered renewed interest in the latest recommendations. Treatment needs to be tailored to not only the parasite but also the immune status of the patient. The overall clinical status of the patient should be considered when deciding on the use of empiric therapy.
is a coocidian parasite that infects a wide range of vertebrate hosts including man. The parasite is now of potential significance from both clinical and public health perspectives in that it causes severe diarrhoea in immunocompromised individuals and can be transmitted from livestock to man. This paper critically examines all the published evidence of cryptosporidium infection in man and animal in Nigeria, in order to ascertain the presence of the zoonosis cycle of the disease. There were ten publications on the prevalence of cryptospodiosis in human patients between 1987 and 2008 in Nigeria, while there yet to be a single evidence of the presence of the disease in animals. All the studies neither identified nor characterized the species of cryptosporidium in their findings and none of the published data examined the possibility of animals being the source of the infection to humans. The limitation of the published studies and the implication of the findings are discussed in this review ...

Cryptosporidium - or Crypto, for short - is a parasite that causes the diarrheal disease cryptosporidiosis. In a new report, the CDC noted 1,788 water-associated illnesses were reported between 2011 and 2012, including 95 cases that required hospitalization and one death in 32 states and Puerto Rico. Of those, the agency said Cryptosporidium was responsible for more than half the cases stemming from treated water in pools and hot tubs. While most bacteria can live in treated water for only a few hours at most, Cryptosporidium can hang on for up to 10 days. Its protected by an outer shell that allows the parasite to survive for up to 10 days even in chlorine-treated water, so even well-maintained pools can spread Crypto among swimmers. To be safe, the CDC advises checking to see when the pool youre using was most recently inspected. Be sure you or your children dont swallow water while swimming.

I work with Cryptosporidium (oocysts), a protozoan parasite that primarily causes Cryptosporidiosis in humans and other hosts. It can be fatal to immuno-compromised and immuno-suppressed hosts such as patients with AIDS, Cancer, Transplanted organs, etc. So far, the excystation mechanism is incompletely understood. Thus, learning about excystation can lead to a better understanding of environmental persistence and host specificity of Cryptosporidium. It can also help scientists to identify environmental and chemotherapeutic interventions. As a researcher of C. parvum, I am attempting to examine what triggers excystation and explore the post-translational differences between unexcysted and excysted oocysts ...
Citation: N/A Interpretive Summary: Technical Abstract: Cryptosporidium parvum is a protozoan parasite that causes intestinal infection and diarrhea in over 150 species of mammals, including humans and economically important livestock species. There are no effective vaccines or drug treatments available for this parasite. Cryptosporidium parvum has been shown to utilize a metabolic pathway not found in mammals for the synthesis of polyamines, forming agmatine as an intermediary metabolite. Thus, interference with this pathway may compromise the parasite, with minimal effects on the mammalian host. In the present study, we treated infant mice with oral doses of agmatine for 2 days before, the day of, and 5 days following, experimental infection with C. parvum. Mice treated with agmatine were significantly less infected with C. parvum than were control mice. Mice treated with agmatine only on the day of experimental infection with C. parvum were also significantly less infected than were control ...
Chronic intractable diarrhea, fever, malaise, and weight loss are symptoms with E. bieneusi infections, symptoms that are similar to those seen with cryptosporidiosis or isosporiasis. AIDS patients tend to have four to eight watery, nonbloody stools which can be accompanied by nausea and anorexia. There may be dehydration with mild hypokalemia and hypomagnesia, as well as d‑xylose and fat malabsorption. The patients tend to be severely immunodeficient, with a CD4 count always below 200 and often below 100. A dual infection with E. bieneusi and E. intestinalis has also been reported. Once the primary infection has been established, the immune status of the host plays a very important role in determining the length and severity of the illness. Patients infected with Cryptosporidium spp. may also have concurrent infections with microsporidia, and this number may approach 30%. These findings emphasize the importance of considering both organisms as potential causative agents of diarrhea in ...
Cryptosporidiosis is caused by Cryptosporidium, or "crypto," a parasite that causes watery diarrhea. The parasite is found in the fecal matter of people infected with crypto, and it is spread by swallowing contaminated water or by human-to-human contact.. Symptoms include watery diarrhea, abdominal pain and cramping, dehydration, weight loss, fever and nausea and vomiting.. Symptoms can last for two weeks. Infected persons can continue to spread the disease for several weeks after diarrhea, so they should avoid activities involving recreational waters for at least two weeks after diarrhea subsides and practice diligent hand washing.. This outbreak is not tied to any one location. Most cases report multiple exposures at various recreational water facilities throughout the three jurisdictions.. Related: ...

Rapid identification of the two major species of Cryptosporidium associated with human infections, Cryptosporidium hominis and Cryptosporidium parvum, is important for investigating outbreaks of cryptosporidiosis. This study reports the development and validation of a real-time PCR TaqMan procedure for detection of Cryptosporidium species and identification of C. hominis and C. parvum in stool specimens. This procedure comprised a generic TaqMan assay targeting the 18S rRNA for sensitive detection of Cryptosporidium species, as well as two other TaqMan assays for identification of C. hominis and C. parvum. The generic Cryptosporidium species assay can be duplexed with the C. parvum-specific assay. The generic Cryptosporidium species assay was able to detect ten Cryptosporidium species and did not cross-react with a panel of ten other protozoan parasites. The generic Cryptosporidium species assay could detect 1-10 oocysts in a 300 μl stool specimen, whilst each of the species-specific TaqMan assays had
Giardia lamblia and Cryptosporidium parvum are both waterborne pathogens associated with diarrhoea in developing countries. In a recent study based at the Aga Khan University in Karachi, 334 adults aged 16-83 years (178 Patients with chronic diarrhoea and 156 diarrhoea-free volunteers who acted as controls) were checked for infection with these parasites, using stool microscopy and/or PCR. Overall, 21 (6.3%) and 29 (8.7%) of the subjects were found positive for G. lamblia by microscopy and PCR, respectively, while the corresponding values for C. parvum were 13 (3.9%) and 14 (4.2%). Although, compared with the diarrhoea-free controls, the Patients with diarrhoea were not significantly more likely to be found infected with Giardia, either by microscopy [15 (8.4%) v. six (3.8%), P=0.085] or PCR [19 (10.7%) v. 10 (6.4%), P=0.167], they were significantly more likely to be found infected with C. parvum, both by microscopy [11 (6.2%) v. two (1.3%), P=0.024] and by PCR [12 (6.7%) v. two (1.3%), P=0.014].The 19
Over the course of six months wild filth flies were collected from traps left for 7-10 days in a barn with or without a calf shedding Cryptosporidium parvum Genotype 2 oocysts in diarrheic feces. The oocysts of C. parvum transported on the flies' exoskeletons and eluted from their droplets left on visited surfaces were infectious for mice. The mean number of oocysts carried by a fly varied from 4 to 131, and the total oocyst number per collection varied from 56 to approximately 4.56 x 10(3). Fly abundance and intensity of mechanical transmission of infectious C. parvum oocysts were positively correlated, and both increased significantly when an infected calf was in the barn. Molecular data showed that the oocysts shed by infected calves were carried by flies for at least 3 weeks. Filth flies can acquire infectious C. parvum oocysts from unsanitary sites, deposit them on visited surfaces, and therefore may be involved in human or animal cryptosporidiosis.
To compare the diagnostic sensitivity and specificity of seven Cryptosporidium diagnostic assays used in the UK, results from 259 stool samples from patients with acute gastrointestinal symptoms were compared against a nominated gold standard (real-time PCR and oocyst detection). Of the 152 true positives, 80 were Cryptosporidium hominis, 68 Cryptosporidium parvum, two Cryptosporidium felis, one Cryptosporidium ubiquitum and one Cryptosporidium meleagridis. The Cryptosporidium spp. diagnostic sensitivities of three Cryptosporidium and Giardia combination enzyme immunoassays (EIA) coupled with confirmation of positive reactions were 91.4-93.4 %, whilst the sensitivity of auramine phenol microscopy was 92.1 % and that of immunofluorescence microscopy (IFM) was 97.4 %, all with overlapping 95 % confidence intervals. However, IFM was significantly more sensitive (P = 0.01, paired test of proportions). The sensitivity of modified Ziehl-Neelsen microscopy was 75.4 %, significantly lower than those for the
Cryptosporidium parvum is a waterborne coccidian protozoan parasite known to infect humans, resulting in an illness known as cryptosporidiosis. The widely used USEPA method 1622 to detect Cryptosporidium is time consuming, and unable to provide the information on oocysts viability and species. In order to develop a fast detection method for viable C. parvum oocysts, a 0.2 μm pore size hollow fiber membrane and 0.45 μm pore size disc membrane were used to filter tap water. Modified Immunomagnetic separation (IMS) purification was followed, and the IMS condition was optimized to shorten the purification time. Finally, fluorescence in situ hybridization (FISH) and FITC-conjugated monoclonal antibody (FMAb) staining were combined to detect viable oocysts, and results indicated that the viable oocysts detection by FISH/FMAb can be achieved in 20 min. The total viable oocysts detection time can be shortened to less than 1.5 h without affecting oocysts recovery. © IWA Publishing 2011 ...
This report aims to propose a new species of Cryptosporidium isolated from reptiles. Cryptosporidium spp. are apicomplexan parasites of a wide range of animals. Due to their biology, ecology and epidemiology these protozoa are globally distributed. The vertebrate hosts become infected through host-to-host contact or through ingestion of contaminated food or water [1, 2]. The taxonomy of Cryptosporidium has been debated and several doubts and uncertainties still exist. For a long time the only recognized species have been Cryptosporidium parvum and Cryptosporidium muris. However, numerous other isolates were present in animals but described only in the last decades [3]. The difficulties in addressing Cryptosporidium taxonomy and in delineating new species mainly rely on the inability to morphologically discriminate the biological stages and on the difficulties in establishing monospecific experimental infections [3]. With the advent of nucleic acid-based techniques and sequencing, important ...
The present study indicated Cryptosporidium infection in pigs in Shaanxi province, with an overall infection rate of 3.3%, showing a lower infection rate than that in Henan (8.2%) and Anhui (56.8%) provinces, China [20,21]. Compared with the prevalence of Cryptosporidium infection in pigs in other countries, it was relatively lower than that in western Australia (6.0%), northeastern Spain (22.5%), and Denmark (16%, 31%, and 100% for sows, piglets, and weaners) [22-26], but higher than that in Germany with the prevalence of 1.4% [27]. Many factors have been considered to influence the prevalence of pig cryptosporidiosis among different areas and countries, including pig health status, age categories, breeding mode, and management style [28,29].. Cryptosporidium species have been molecularly genotyped in pigs in many countries, including China [20,22,23,30]. C. suis, C. scrofarum, C. muris, C. tyzzeri, C. parvum, and C. andersoni were successfully isolated and identified [25,31-35]. However, DNA ...
There are only limited number of reports on molecular epidemiology of Cryptosporidium spp. and Giardia duodenalis in dogs and cats in China. This study was conducted to assess the infection rates, genetic identity, and public health potential of these parasites in dogs and cats in Guangdong, China. PCR and sequence analyses were used to identify and genotype Cryptosporidium spp. and G. duodenalis in fecal samples from 641 dogs and 418 cats in Guangdong. Chi-square test and odds ratio analysis were used to compare the occurrence rates of these pathogens and identify risk factors for infection. The overall infection rates of Cryptosporidium spp. and G. duodenalis were 6.9% (44/641) and 9.4% (60/641) in dogs, and 6.2% (26/418) and 3.6% (15/418) in cats. Purebred cats (12.4%; χ2 = 5.110, OR = 2.8, P = 0.024) and dogs (10.8%; χ2 = 5.597, OR = 4.8, P = 0.018) were more likely to be infected by Cryptosporidium spp. and G. duodenalis, respectively. Dogs (12.0%; χ2 = 7.589, OR = 2.6, P = 0.006) and cats (13.6

Diarrhoea caused by Cryptosporidium is usually mild in immune competent individuals but severe in the young and those with underlying disease leading to compromised immunity. The conventional diagnosis of Cryptosporidium requires observation of the infective oocysts however, their tiny size yields indistinct results, thus limiting the effectiveness of the conventional diagnostic technique, modified Ziehl-Neelsen (ZN) differential staining. Consequent to the abovementioned limitation, ZN staining, sandwich antigen detection enzyme linked immunosorbent assay (sad-ELISA) and a direct polymerase chain reaction (PCR) assay techniques were evaluated for diagnostic efficacy. Stool samples were collected from 180 consenting adult patients attending outpatient and inpatient clinics at Victoria Hospital, Alice, Eastern Cape Province of South Africa. Subjects were stratified as; 35 HIV-positive and diarrhoeagenic, 125 HIV-negative diarrhoeagenic and 20 apparently healthy controls. Cryptosporidium incidence

Cryptosporidium spp. are intracellular parasites that primarily infect epithelial cells of the stomach, intestine, and the biliary ducts. In severely immunocompromised persons, the respiratory tract is sometimes involved. Cryptosporidium spp. have a worldwide distribution, and their oocysts are ubiquitously present in the environment. Transmission of C. hominis is mostly from person-to-person (anthroponotic) where as C. parvum is typically zoonitic from livestock to humans. Exposure occurs through fecal-oral transmission by animal to human, waterborne (typically spring and late summer due to recreational water exposure), foodborne (mostly associated with fruits, vegetables, shellfish, and unpasteurized apple cider and milk) and person-to-person.. Cryptosporidiosis occurs in patients with acquired immunodeficiency syndrome (AIDS) and as a self-limited moderate diarrhea in young children, especially daycare attendees and their relatives. Cryptosporidiosis can cause a profuse and watery diarrhea, ...

The coccidian genera that cause disease in humans include Cryptosporidium, Cyclospora, Isospora, Sarcocystis, and Toxoplasma. What was previously called Cryptosporidium parvum and was thought to be the primary Cryptosporidium species infecting humans is now classified as two separate species, C. parvum (mammals, including humans) and Cryptosporidium hominis (primarily humans). Evidence obtained from excystation experiments indicates that the oocyst contains two sporocysts, each containing two sporozoites, a pattern which places these organisms in the coccidian genus Cyclospora. Electron microscopy (EM) confirmed the presence of characteristic organelles for coccidian organisms of the phylum Apicomplexa. Phylogenetic studies have confirmed that the microsporidia evolved from the fungi, being most closely related to the zygomycetes. Microsporidia have extremely small genomes, very similar to those seen in bacteria. A variety of serologic tests have been used to detect immunoglobulin G (IgG) and IgM

Fecal specimens for parasitic examination should be collected before initiation of antidiarrheal therapy or antiparasitic therapy. The highest yield on hospitalized patients occurs when diarrhea is present on admission or within 72 hours of admission. The onset of diarrhea more than 72 hours after admission is usually caused by Clostridium difficile toxin rather than parasites or the usual stool pathogens. The following recommendations are made for efficient and cost-effective diagnosis of diarrheal disease in patients admitted with gastroenteritis.. • Submit one or two specimens per diarrheal illness immediately. Consider first requesting EIAs for Giardia and Cryptosporidium (See test Giardia lamblia, Direct Detection EIA [182204] or Giardia lamblia, Direct Detection EIA and Cryptosporidium, Direct Detection EIA [183558]). Giardia and Cryptosporidium are the most common causes of parasitic gastroenteritis in the United States.. • If EIAs are negative, request add-on testing for Ova and ...
The aim of this study was to investigate the occurrence of Giardia duodenalis and Cryptosporidium spp. in primates and determine their zoonotic or anthropozoonotic potential. Direct immunofluorescence was used to identify Giardia and Cryptosporidium from faecal samples. PCR and DNA sequencing was performed on positive results. Giardia cysts were identified from 5.5% (5/90) of captive chimpanzees and 0% (0/11) of captive mandrills in the Republic of Congo; 0% (0/10) of captive chimpanzees in Norway; and 0% of faecal samples (n = 49) from wild Zanzibar red colobus monkeys. Two Giardia positive samples were also positive on PCR, and sequencing revealed identical isolates of Assemblage B. Cryptosporidium oocysts were not detected in any of the samples. In these primate groups, in which interactions with humans and human environments are quite substantial, Giardia and Cryptosporidium are rare pathogens.
